Your home deserves the best!
Whether you’re re-siding your home or building a new one, improper installation is the primary cause of poor product performance and dissatisfaction with your vinyl siding. It can even void manufacturer warranties.
That’s why the Vinyl Siding Institute (VSI) recommends using installers who are certified through the VSI Certified Installer Program.
Vinyl siding is the only exterior cladding with a certified installer program with validation by an independent, third-party administrator to ensure that installers demonstrate knowledge of industry-accepted application techniques.
Certified Vinyl Siding Installers have at least two years of installation experience and have demonstrated knowledge on proper installation techniques consistent with the industry recognized installation standard, ASTM D4756. Certification is valid for three years after which an installer must recertify.
